I would be careful, I purchased mine from NAPA. AES Wave is a good place too. I have read of people having trouble with Amazon and Ebay units. Not sure why.
If you don`t do much J2534,Mercedes and BMW module replacements then purchase a unit without the Jbox. The price is much cheaper plus updates are much cheaper. I would have done that but I wanted the Jbox. Heck I would have been better off purchasing a seperate Jbox, I didn`t realize that Autel wants $1000 for updates when I purchased my unit.
Some people have been claiming that their tool loses functions when their subscription expires. I do know that after your 1 year updates are done you have NO SUPPORT from Autel. People on this forum have been saying to shut off your WiFi when your updates expire because soon as the WiFi connects their tool locks up or loses function and you get NO help from tech support other than, pay up your $1000 if you ever want your tool to work again.
Take some time and read through the posts. I knew none of this before I purchased mine. It would have changed my decision to purchase the tool.
